I have heard one theory that Tabbys star dims is due to an alien megastructure. Where would they get the raw materials to build such a large object?
It is worth reflecting carefully on the meaning of the word alien.zuz said:I doubt the alien theory also. But if you had the resources and energy to build such a structure, why would you need it?

Under what circumstances we are "making stars"? In your giant molecular cloud you have thousands of solar mass. You collapse your cloud as you process it. You need to fling mass away from the cloud in order for it to continue collapsing. Which mass you eject will depend on what product the customer wants delivered.szopaw said:I'm trying to run with this idea and figure out what purpose would making a "blue dwarf" have.

Tabby's star, also known as KIC 8462852, is dimming because of a phenomenon called "Tabby's star dips." These dips are irregular and unpredictable changes in the star's brightness that can range from 15% to 22%.
The exact cause of Tabby's star dips is still unknown, but there are several theories. Some scientists believe it could be caused by a swarm of comets or other objects passing in front of the star, while others suggest it could be due to a large dust cloud orbiting the star.
No, Tabby's star is not dimming at a consistent rate. The dips in brightness are irregular and can happen at any time, making it difficult to predict when the next dip will occur.
The first recorded dip in Tabby's star's brightness was in 2011, but it was not until 2015 that the star's unusual behavior was noticed by scientists. Since then, it has continued to dim sporadically.
While this is a popular theory, there is no evidence to support it. The most likely explanation for Tabby's star dips is a natural phenomenon, but further research is needed to fully understand it.
